1. factor. 100x^2−20xy+y^2 2. factor. 4x^2−49y^2 3. subtract. (x^2+3x−7)−(3x^2−5x+3) 4. multiply. −2x(6x^4−7x^2+x−5) this is really important i need it done by 2/4/2018 1: 00 you (show your work or no points)

1. (10x-y)² (because 100x²=(10x)², and -20xy=-2(10x)*y)
2. (2x+7y)(2x-7y) (because 4x²=(2x)², 49y²=(7y)²)
3. -2x²+8x-10
4. -12x^5+14x³-2x²+10x (use distributive property, multiply every term in the parenthesis by -2x)

Iwould say that is c

What is the question ehre
